GREASE-CUP.

Application filed March 26,1913.

To all whom it may concern:

Be it known that I, NORMAN WV. CUM- MINS, a citizen of the UnitedStates, residing in the city of Bridgeport, county of F airfield, Stateof Connecticut, have invented certain new and useful Improvements inGrease-Cups; and I do declare the following to be a full, clear, andexact description of the invention, such as will enable others skilledin the art to which it appertains to make and use the same.

This invention relates to certain new and useful improvements in greasecups and pertains more particularly to the means for forcing the greasethrough the feed opening.

The primary object of the invention is to provide novel and improvedmeans for feed ing the lubricant, and to further provide novel means forpreventing retrograde rotation of the feeding element.

In the drawings: Figure 1 is a vertical sectional view of the invention;Fig. 2 is a side elevation; Fig. 3 is a section on the line 33 of Fig.2; Fig. 4L is a section on the line of Fig. 2; Fig. 5 is a section onthe line 5-5 of Fig. 2; and Fig. 6 is a fragmentary perspective viewshowing one of the ratchet teeth of the spring-held sliding collar.

The body 1 is formed with a reduced exteriorly threaded lower end 2 thatis pro-' vided with an outlet opening 3, a collar or abutment i beingsuitably secured at the upper portion of the reduced end 2. The upperend of the body is formed with an outwardly extending flange 4 thatengages with a flange 5 which extends inwardly from a reinforcing member6, the free upper end portion of the member being forced inwardly toengage on top of the flange 4 whereby the latter is clamped between theflange 5 and the flange 7 that is formed by forcing said upper endportion of the member 6 inwardly. The periphery of the reinforcingmember 6 is exteriorly threaded and is engaged with a cap 8 that has ahexagonal head 9 to allow same to be manually rotated. The lower end ofthe cap 8 is offset or expanded at 10 so as to extend outwardly from themajor portion of the cap, and the lower edge of said offset portion 10is formed with cut-out portions 11 to provide ratchet teeth, which arepreferably two in number. A knurled collar 12 is formed with a hexagonalopening 13 at its center in Specification of Letters Patent.

Patented July 27, 1915. Serial No. 756,988.

order to allow the collar to have sliding movements lengthwise of thebody 1, but to prevent rotary movement thereof relative to the body.

A. feature of the present invention consists in striking or pressing outratchet teeth 14: from the body portion of the collar, which teeth areinclined with respect to the plane of the body of the collar in order toallow the ratchet teeth of the cap 8 to ride easily thereover. Theratchet teeth 1-1 which are struck out from the body of the collar 12are closed on both sides, their front ends and the tops thereof, whichresults in maxi mum strength being imparted to the teeth, and increasedwearing ability. A somewhat conical spring 15 has its lower end seatingon the flange i and its upper end bearing against the body of collar 12,and being also engaged by the inner face of the knurled portion of saidcollar.

By expanding or offsetting the lower end or the bottom portion of thecap, as above described, the cap is materially strengthened, and byforming the ratchet teeth on this expanded portion, the threads on theinterior of the cap, are not interfered with or mutilated, in movementof the collar to the position where it abuts flange 5, or in movement ofthe cap to disengage same from the body, due to the fact that theratchet teeth are located in a plane outside of or spaced from the planein which the threads of the cap are located.

The body 1 is reduced above the abutment 4 at a to form a shoulder 6,whereby, when it is desired to refill the body 1 with grease, collar 12is forced downwardly against the action of the spring 15, to bring theopening of the collar 12 opposite to the reduced part a of the body 1,whereupon the collar is slightly turned to engage beneath the shoulder 6to thus lock the collar against the action of the spring. The collar maybe then rotated backwardly and removed. It will be apparent that theformation of the ratchet teeth is such that clockwise move ment only ofthe cup 8 is permitted.

What is claimed is:

In a grease cup, a body of angular crosssection having a threaded upperend, and an abutment adjacent its lower end, a shoulder on the body andspaced above the abutment, a collar extending in a plane at right anglesto the longitudinal axis of the body offset end of the cap to provide anexposed Copies of this patent may be obtained for hand gripping partwhich enables the collar to be depressed and partially rotated to engageunder the shoulder whereby to hold the collar inoperative during removalof the Cap and filling of the cup.

In testimony whereof I aflix my signature in presence of two witnesses.
